Summary
Personalized 3D-printed hemipelvic prostheses offer a promising alternative for treating peri-acetabular malignant bone tumors, achieving acceptable functional outcomes with manageable complications.
Area of Science:
- Orthopedic Oncology
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Peri-acetabular malignant bone tumors present significant treatment challenges.
- Prosthetic reconstruction is a potential solution but carries a high complication rate.
- Optimizing prosthetic design and reconstruction techniques is crucial.
Purpose of the Study:
- To evaluate the efficacy and safety of personalized 3D-printed hemipelvic prostheses for peri-acetabular malignant bone tumors.
- To assess functional outcomes, pain reduction, and complication rates following this reconstructive approach.
Main Methods:
- Retrospective analysis of 11 patients with peri-acetabular malignant bone tumors.
- Treatment involved en bloc resection and reconstruction with custom 3D-printed hemipelvic prostheses.
- Pain (VAS) and functional (MSTS-93) scores were assessed, alongside complication and recurrence monitoring.
Main Results:
- Average follow-up was 15.5 months.
- Significant pain reduction was observed (VAS pre vs. post: 3 vs. 2).
- Mean MSTS-93 score was 19.2; complications included hip dislocation (2 patients) and delayed wound healing (1 patient). One metastasis was noted, with no local recurrence.
Conclusions:
- Personalized 3D-printed hemipelvic prostheses provide acceptable functional results for peri-acetabular malignant bone tumor reconstruction.
- This approach offers a promising alternative with a manageable complication profile.
- Further research into prosthetic design and reconstruction techniques is warranted.
